Best Outfit for senior pictures?

aside from the classic yearbook picture i have already taken, i need an outfit for my creative senior pictures. My style: casual/preppy if that makes sense. I want the pictures done outside, and i know mostly what ill wear, but its the shirt that i can’t decide on. Jeans with me either barefoot or in boots or zebra print heels. so help me get an idea of a shirt that will work with that, please and thank you:)
